Why are cross connections a problem?
Sump pump water is what engineers refer to as clear water, most often rainwater, ground water, or snow melt. This water is clean enough to drain directly into area streams, ponds, and lakes without treatment. Wastewater, water from your sinks, showers, tubs, toilets, and washing machines, must be treated at your area wastewater treatment plant before it can be safely discharged into the environment.
